CUPOLA.

Application filed October 17, 1913.

To all whom it may concern Be it known that I, FRED H. Hnisn, a citizenof the United States, residing at Manson, in the county of Calhoun andState of Iowa, have invented certain new and useful Improvements inCupolas, of which the following is a specification, reference being hadtherein to the accompanying drawing.

This invention relates to a guard or cover for the opening of a corn binthat admits the corn or other material to the bin.

The object of this invention is to provide a cover of the kind abovedescribed that will efiiciently keep rain or other foreign matter fromenterin the bin.

Another 0 ject of this invention is the production of a strong anddurable cover that will stand the wear in placing the same over andremoving it from the opening in the bin.

With these and other objects in view, this invention consists of certainnovel combinations, constructions and arrangements of parts as will behereinafter fully described and claimed.

In the accompanying drawing :-Figure 1 is a perspective view of thecover in engagement with a corn bin. Fig. 2 is a vertical section of theimproved cover. Fig. 3 is a fragmentary perspective View of one cornerof the cover. Fig. 4: is a perspective view of the bottom plate orprotector for the opening of the corn bin. Fig. 5 is a frag mentary viewof one corner of the blank from which the sections are formed. Fig. 6 isa detailed perspective view of a portion of one of the sections of thecover showing a hinge ear secured thereto. Fig. 7 is a detailedperspective view of a portion of the other section from that shown inFig. 6 showing a hinge ear secured thereto.

Referring to the parts by reference numerals 1 denotes an ordinary cornbin provided with the usual opening or aperture 11 to admit corn or thematerial to said bin. Positioned at the bottom edges of the opening oraperture 11 is a protector plate 12 and secured under the shingles ofthe bin roof along the side edges of the opening 11 are side protectorplates 13. Both the side protector plates 13 and the bottom protectorplates 12 are provided with up-turned flanges 14 running longitudinallytheir lengths. The fiat or body portion of the bottom protector plates12 has an enlarged portion at either end and the side protectorSpecification of Letters Patent.

pletely surrounding the aperture 11 with a flange. The cover or guard ismade of two sections 15 and 16 and are provided with, on the bottom andside edges, outwardly extending flanges 17. Flanges 17 having theirbottom upwardly turned upon themselves to form the reinforcing strip 18.This reinforcing strip 18 also passes over the bentover tongue 19, thusmaking a very substantial and secure corner for the sections. This isclearly illustrated in Fig. 3. The section 15 is provided with adiagonally extending portion or top 20 and has secured on its inner faceadjacent the top 20 hinge-ears 21 secured by the rivet 22. The section16 has turned-over portions forming hingeears and are adapted to fitbetween the hingeears 21 and the section 15, and through said hinge-earspasses a pin 23 which holds the sections together. Secured adjacent thebottom edge of the sections 15 and 16' are handles 2 1, said handlesalso carrying a hook adapted to engage an eye positioned in the bin tosecurely hold the cover thereon.

From the foregoing description it will be seen that a cover for anopening in a corn bin has been provided that is very strong and durableby means of the strip 18 and the bent-over tongue 19. There is alsoprovided a cover that will absolutely exclude water and other foreignmatter from the bin. This is accomplished by having the side plates 13positioned under the shingles adjacent the edge of the opening 11 as faras indicated by the dotted lines in Fig. 1, and by also having thebottom protector plate 12 secured at its ends beneath the shingles byhaving its body proper above the row of shingles beneath the row towhich its ends are secured. The cover or top 20 also insures awatertight cover inasmuch as the same rests snugly against the section16 when in an extended position as shown in Fig. 1.

It is obvious that minor changes may be made in the form andconstruction of this invention without departing from the spiritthereof. It is therefore not wished to confine the invention to theexact form herein shown and described but it is wished to include allsuch as properly come within the scope claimed.

Having thus described the invention, What is claimed as new, is

A device of the class described comprising a primary and an auxiliarysect-ion, said sections provided With rigid flanges at their side edges,said primary section provided With a diagonally extending overhangingtop flange, said top flange being held rigidly in a diagonal position bymeans of the remaining flanges of said primary section, a plurality ofhinge ears fixedly secured Within said primary section adjacent theinner portion of said overhanging top, said auxiliary section providedWith integral hinge sleeves formed upon its inner upper portion, saidhinged sleeves fitting between the hinge ears of the primary section, apin passing through said sleeves for hingedly securing said sectionstogether, said diagonal top flange of the primary section overhangingthe hinged portion of said section, thereby preventing the Water frompassing between the said hinged portions, said diagonal overhanging topconstituting a stop for the auxiliary section as the same swings in onedirection thereby limiting the swinging of said section for preventingthe device from opening beyond a predetermined point.

In testimony whereof I hereunto affix my signature in presence of twoWitnesses.
